This four-session workshop covers the best known optic-neuronal visionary techniques to date --phenomena widely acknowledged by contemporary science and advanced visual meditation techniques which have been highly valued in diverse traditions and places through time because of their effectiveness for attaining enlightenment.

Manu discovered most of these techniques intuitively during his childhood and adolescence, without knowing they were spiritual techniques, and he learn the rest as advanced yoga practices during his Himalayan retreats. Most of the techniques are based on physiological processes that involve making the eyeball still. This "cheats" the brain, which believes it is experiencing deep sleep, allowing the person to enter samadhi or mystic absorption, manifesting a state similar to deep sleep, but without losing consciousness. This comes together with and it is mutually reinforced by the learning of a vision in different levels or layers of depth or planes, without the help of the eye lense but rather as the result of variations in the practitioner's perceptual consciousness states.
